2. Key Adventages
Stabilized with Titanium (Ti) to effectively prevent intergranular corrosion in the carbide precipitation sensitization range (450-850°C). Ideal for components that cannot be solution annealed after welding.
Superior High-Temperature Performance
It maintains good oxidation resistance, creep resistance and long-term strength even at high temperatures, making it a reliable choice for boiler, superheater and heat exchanger tubes.
Annealed in a controlled atmosphere furnace resulting in a smooth, bright, and scale-free surface. This finish is easy to clean, reduces the risk of product contamination, and enhances corrosion resistance.
Manufactured with advanced welding and cold-reduction processes ensuring tight dimensional tolerances, uniform wall thickness, and excellent concentricity.
Good resistance to a wide range of organic and inorganic chemicals, as well as oxidizing media.
